Description

Es wurde gefunden, daß man 3,6-Endoäthylenpr !^^,S-cyclohexantetracarbonsäure-dianhydriderhält, wenn man zl-S^-trans-Cyclohexadien-ljS-dicarbonsäure mit Maleinsäureanhydrid in Gegenwart von Essigsäureanhydrid bei Temperatoren vpn 50 bis 150° C umsetzt. Vorzugsweise werden Temperaturen von 80 bis 130° C eingehalten.It has been found that 3,6-Endoäthylenpr ! ^^, S-cyclohexanetetracarboxylic acid dianhydride contains, if one zl-S ^ -trans-cyclohexadiene-ljS-dicarboxylic acid with maleic anhydride in the presence of acetic anhydride at temperatures from 50 to 150 ° C. Temperatures of 80 to 130 ° C. are preferably maintained.

Das 3,6 -Endoäthyleno -1,2,4,5 - cyclohexantetracarbonsäure-dianhydrid fällt in Form weißer, sehr reiner Kristalle, die nicht mehr umkristallisiert werden müssen, aus der Mischung aus. Es dient als Härter für Epoxyharze und ist ferner für die Herstellung von Polyestern und Polyimiden verwendbar.The 3,6-endoethyleno -1,2,4,5-cyclohexanetetracarboxylic acid dianhydride falls in the form of white, very pure crystals that are no longer recrystallized need to get out of the mix. It serves as a hardener for epoxy resins and is also used in manufacturing of polyesters and polyimides can be used.

Aus der deutschen Patentschrift 526 168, Seite 7, Beispiel 28, ist die Umsetzung von .4-3,5-CiS-CyCIohexadien-l,2-dicarbonsäureanhydrid mit Maleinsäureanhydrid zum 3,6rEndpäthylenprl,2,4,5rCyclphexanr tetracarbonsäure-dianhydrid in der Schmelze bekannt. Bei diesem Verfahren fällt das Umsetzungsprodukt in wenig reiner Form an und muß wegen der Schwerlöslichkeit der Endoäthylenverbindung mit Hilfe großer Mengen teurer organischer Lösungsmittel umkristallisiert werden. Eine Übertragung des Verfahrens auf die trans-Verbindung ist nicht möglich, da diese sich leicht in die resonanzstabilisierte A-2,6-Cyclohexadien-1,2-dicarbonsäure umlagert. Eigene Versuche mit der AS^-tian^-Cycldhexadienr 1,2-dicarbonsäure bestätigten dann die Erwartung, daß diese Säure einer Dien-Synthese nicht zugänglich ist.From the German patent 526 168, page 7, example 28, the implementation of .4-3,5-CiS-CyCIohexadien-1,2-dicarboxylic anhydride with maleic anhydride to 3,6rEndpäthylenprl, 2,4,5rCyclphexanr tetracarboxylic acid dianhydride in the Known melt. In this process, the reaction product is obtained in a poorly pure form and, because of the poor solubility of the endoethylene compound, has to be recrystallized with the aid of large amounts of expensive organic solvents. It is not possible to transfer the process to the trans compound, since this easily rearranges into the resonance-stabilized A-2,6- cyclohexadiene-1,2-dicarboxylic acid. Our own experiments with the AS ^ -tian ^ -Cycldhexadienr 1,2-dicarboxylic acid then confirmed the expectation that this acid is not amenable to a diene synthesis.

Es war überraschend, daß bei Gegenwart von Essigsäureanhydrid nicht nur die unerwünschte Umlagerung in die /1-2,6-Verbindung vermieden, sondern auch ohne besondere zusätzliche Maßnahmen die gesuchte Endoäthylenverbindung direkt hergestellt werden kann.It was surprising that in the presence of acetic anhydride not only the undesired rearrangement avoided in the / 1-2,6 connection, but also without special additional measures the endoethylene compound sought can be produced directly.

Wenn diese Temperatur erreicht ist, liegt eine klare Lösung vor, die nun bis auf 125° C weitererhitzt wird. Man hält diese Temperatur während 3 Stunden aufrecht, wobei nach 10 Minuten die ersten Kristalle abgeschieden werden, kühlt dann die Mischung auf gewöhnliche Tempe-Analysenwerte: 42 parts / 1-3,5-trans-cyclohexadiene-1,2-dicarboxylic acid and 24.5 parts of maleic anhydride are mixed with 300 parts of acetic anhydride and below Stirring heated to 80 ° C. When this temperature is reached, there is a clear solution, which is now up to is further heated to 125 ° C. This temperature is maintained for 3 hours, after which 10 minutes the first crystals are deposited, then the mixture cools to normal temperature analysis values:
